Abstract: A primary purpose of the present investigation was to demonstrate that certain physiological and behavioral variables tend to change concordantly with experimentally-induced changes in activation and to show further that these same variables may be simultaneously influenced by other factors in an independent and specific manner. Activation level was altered by varying the difficulty as well as the incentive of the task. This was accomplished by having S watch a flashing light while: (a) maintaining a relaxed, quiescent state; (b) releasing a key in response to a flash; and (c) releasing a key under threat of shock. Heart rate, muscle tension, skin conductance, evoked cortical responses, and reaction times were recorded simultaneously for each of six Ss under all three conditions.
